ABB Miniature Circuit Breakers
Miniature circuit breakers (MCB) are electrical switches that are designed to trip during a short circuit or overload to protect against electrical faults and equipment failure. Overload protection is accomplished through a thermal operation with a slight time delay. When an overcurrent passes through an MCB, a bimetallic strip is heated and bends. The bending causes a mechanical latch to release, opening the MCB contacts, halting the flow of current. When the overcurrent is removed, the contacts close and the MCB is reset. Short circuit protection is accomplished through an electromagnetic operation that is instantaneous. A current coil is tripped causing the mechanical release of the latch that opens the contacts that halt the flow of current. When the overcurrent is removed, the MCB can be reset.
ABB Miniature Circuit Breakers offers an extra-wide and complete range of miniature circuit breakers to cover most applications and markets with breaking capacities up to 25 kA and rated currents up to 100 A.

THQP breakers are a smaller, smarter solution for today's cost- and quality-conscious contractors and homeowners. Half the width of standard breakers, they allow use of smaller load centers and for maximum savings of space and money. GE is the only manufacturer that gives you this cost advantage without sacrificing flexibility. THQP breakers are one-half the width of standard GE breakers but identical in design. They are available from 15 to 50 amps and in single and two pole construction. P145 Amps 45 A
